Hey everyone,

I got an idea but need some validation before working on it. It's to basically build a otp verification system which will handle expiry,rate limiting,multiple sms providers,callbacks etc for email and sms

It will be like

Post{"to":"+123467890","channel"="sms"}

Then to verify

Post{"id":"hdjdj1234","code"="1235"}

Would you use this?

What would you pay for it?

What features would make you choose over twilio verify?

Honest feedback appreciated both good and bad

Me and my friends wanted to start a small ad agency. We needed software to manage digital screens — display ads, schedule them by time of day, that kind of thing.

Existing tools like Yodeck charge for every screen. For a small setup that's just too expensive.

So I built my own tool called Adbook. It's free to use and lets you:

- Upload images and videos as ads

- Schedule them by time slots (morning/afternoon/evening)

- Manage multiple screens from one dashboard

- Works for both horizontal and vertical screen orientations

It's simple and built for my own use case, so I'd love to know if anyone else finds it useful. If you have a shop, restaurant, or office with a display screen, give it a try.

Feedback and suggestions welcome — what features would make this useful for your business?

Me and my friends wanted to start a small ad agency. I looked around for digital signage software and found Yodeck — but it was only free for 1 screen. The paid options were way too expensive for what we needed.

So I just built it myself.

It's a simple digital signage tool that lets you:

- Upload ads (images & videos)

- Schedule them by time slots (morning/afternoon/evening)

- Manage multiple screens from a dashboard

- Supports both horizontal (16:9) and vertical (9:16) displays

It's built for my exact use case so it's pretty simple right now. But it works, it's free, and I'd love to know if anyone else finds it useful.

If you have ideas or recommendations for features I should add, please let me know. Happy to hear any feedback!
